我正在尝试用Ruby构建一个简单的、选择自己的基于冒险的终端应用程序。

我正在使用tty提示发布问题并给出选项-

puts "The road forks here brave #{name} and which of these three roads into the Mirkwood you take"
puts "will be the first of many choices you must make on your journey."
puts " "                                                                                                    
puts " "

end

prompt = TTY::Prompt.new

choices1 = {The_north_road: 1, The_middle_road: 2, The_south_road: 3}
choice = prompt.select("Which road do you choose?", choices1)

我想根据选择引出一个字符串，字符串存储在另一个ruby文件中。然而，这似乎并不奏效。选择会导致意外的输入。

错误=game.rb:117:语法错误，意外的"="，应为"；"或'\n'next_fork=item.paraght1 if choice==1–

任何帮助都将不胜感激。

Answer 1

您发布的错误指的是game.rb:117。game.rb文件中的第117行。你添加到问题中的game.rb只有100行，但我想你在发布之前已经删除了一些代码。如果你转到game.rb文件中的第117行，你会发现：

def
next_fork = item.paragraph1 if choice == 1
next_fork = item.paragraph2 if choice == 2

在ruby中，关键字def定义了一个方法，但它也需要一个名称。Ruby假定next_fork是方法的名称，因为这是def之后的第一个名称。在那之后，有一个=，它不能刚好出现在方法定义之后，并且是语法错误。这就是鲁比要告诉你的。

game.rb:117: syntax error, unexpected '=', expecting ';' or 'n' next_fork = item.paragraph1 if choice == 1

为方法指定一个名称。
